优美树猜想的计算方法

A Computational Approach to the Graceful Tree Conjecture

Wenjie Fang

摘要:

优美树猜想是图论中一个著名的公开问题。在这里,我们提出了一个计算方法,这个猜想。提出了一个求树优美标号的算法。利用这个算法,我们证明了每一棵顶点数不超过35的树都允许优美标号,从而证明了优美树猜想对顶点数不超过35的树是正确的。

英文摘要:

Graceful tree conjecture is a well-known open problem in graph theory. Here we present a computational approach to this conjecture. An algorithm for finding graceful labelling for trees is proposed. With this algorithm, we show that every tree with at most 35 vertices allows a graceful labelling, hence we verify that the graceful tree conjecture is correct for trees with at most 35 vertices.
